Nickel cobalt manganese (NMC523) hydroxide is a chemical precursor of the cathode active material in lithium-ion batteries; this dataset includes major raw materials, auxiliaries, energy, and wastewater treatment in the production process, but the infrastructure such as the manufacturing of production equipment and construction of buildings is not included within the boundary of this dataset; the data inventory is formed by merging data from multiple sources; the synthesis of the ternary precursor adopts the co-precipitation method, using nickel salt, cobalt salt, and manganese salt as raw materials, mixed in a certain ratio with precipitants (such as sodium hydroxide, etc.) and then reacting under certain conditions to form the precipitate of the ternary precursor, which is subsequently washed, filtered, and dried to obtain the ternary precursor. Solid powder.
